When Turbo is enabled on the Phenom II X6 then the idle voltage is quite high.

Undervoltage:

The Phenom II X6 1100T is still nicely under-voltaged. With 0.1V less, it's still stable, but of course you need to disable Turbo.

The Phenom II X4 840 aka Athlon II X4 650 disappoints. With its upped VCore of 1.4000V it only manages 1.3250V, which will still shave off some watts but of course 3.2GHz does need power.

Overclocking:

This Phenom was the first we got to 4GHz, booting up with more than 4GHz was possible, but Prime95 was not stable. Our board is not the greatest overclocker but the results are still impressive for a six core CPU.
